Description
BNC to BNC DC Block | Bayonet-lock | Brass Body
The ROSNOL DB-B1B25A-3G50V/H44-H4 is a precision-engineered DC Block connector featuring a BNC plug (male) to BNC jack (female) interface. Designed for RF applications up to 3 GHz, it maintains a 50 Ω impedance and supports a DC voltage rating of 50V. With a VSWR of ≤ 1.2 and insertion loss ≤ 0.2 dB, this connector ensures reliable signal transmission and effective DC isolation. The bayonet-lock coupling mechanism provides quick and secure mating, ideal for frequent connect/disconnect operations.Constructed with phosphor bronze center contacts with gold plating over nickel underplating; brass body and coupling nut with copper-tin-zinc alloy finish; PTFE insulators; silicone rubber gasket. Operating temperature ranges from -55°C to +90°C, and the product is fully RoHS compliant.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
